For those few of you who haven't already heard the news via other blogs, here it is: Wizards of the Coast is reprinting not just the Gygaxian AD&D rulebooks next month, they're also reprinting the v.3.5 books in September.
I have no insights into WotC's motivations, so I won't hazard a guess as to why the company is doing this. I'll only say that I'm glad of it, even though I'm not a fan or player of 3.5e. My fond dream would be to see WotC reprint and (at least minimally) support several versions of Dungeons & Dragons. I think that's be the ideal way to pay homage to the game's nearly forty year history. It'd also be an ideal way to regain the trust and interest of gamers who are devoted to an earlier edition. Goodness knows I'd be much more likely to buy reprints of certain older products than I ever would be to buy 5e.
Now, I don't expect that either the 1e or v.3.5 reprints are anything but one-time events, but a guy can dream, can't he?
